FILM-Darius .are.liniizrusl Y application ined iuiy i4,

This invention relates to a 'ilm drying and rewinding machine, particularly one in which films which have been joined together in a ilm printing machine are dried and scparated and eventually rewound.

rhe invention in its preferred embodiment is illustrated in the accompanying drawings, which form part of this specification and in which:

Figs. 1 and 1 represent a plan view of the entire machine;

Figs. 2 and 2 represent a side elevation thereof; 4 v

Fig. 3 represents an elevation of the right end of the machine. y

Fig. 4 represents a front elevation of the same end as in Fig. 3;

Fig. 5 represents a side elevation ot the rear end of the machine;

Fig. 6 represents a plan view thereof;

Fig. 7 is a section ofV the center or' the machine where the separation of lilms takes place;

Fig. 8 shows plan views thereof; and

Fig. 9 shows sections along the line 9 9 in Fig. 7 showing the iilms positioned within the drying chamber and also the position ot' the separating roller with respect to the ilms.

In the preferred embodiment of the invention, there is shown a framework denoted generally by the numeral 1 which supports two long vdrying chambers rectangular in section denoted by the numerals 2 and 3. These drying vchambers may be supplied with a drying medium such as air or heated gases by means of an electrically operated blower mechanism 4; in the rear of the apparatus and an electrically operated suction device 5 at the front thereof communicating by vertical channels 6 and 7 with the l1orizout-al drying chambers 2 and B. At the front end of the apparatus there are pro* vvided rollers designated by the numeral 8 over which the incoming iilm is passed on its way through an inclined and enclosed passageway 9 leading to the horizontal passageway or chamber 2 and joining it at a point designated by the numeral 10.. At this point .there is mounted a roller 11 which functioiis i to permit a separation ofthe films, in thev case where a master film and a printed iilni have been joined together or to separate a film from a supporting tape or belt. 'In the case illustrated the belt and printed /tihn i923. seriaiivo. $512,500. I

form a support i'or the master film. VThe master film is returned to the front end. ot the apparatus along the inside of the chamber 2 and over a roller 12 to therewind-v ing reel 13. The printediilin which is here designated by the numeral le passes to the other end of the chamber 2 in contact with a supporting fabric which is provided in the form ofan endless belt to support the film in its transit through the dryingeap aratus. The fabric and film pass around a orizonn tally mounted pulley 15 and lthen enter the drying chamber 3, which they traverse tc the film is rewound ona reel 17. The pulleyl 15 is driven by a inion 18 in mesh with a worm 18 mounts on a shatt 19, which is rotated by aA motor 20 in a suitable manner, and o'n this shaft 19 is provided a gear 21 meshing with a gear 22 on a shaft 23 which extends'the entire length of the machine and carries at its other end a bevel pinion 24 in mesh with a bevel gear 25 mounted on a,

shaft 26 supporting the reels and acting as a driving means therefor. The reels are driven through a friction clutch mechanism comprising discs 27 and 28 held by springs '15,'and then-goes through the drying chainber 3, overthe small pulley 16,; and then down around a .pulley 31, over a small roller 32; and back into the, passageway,9.v The incoming films passing over the roller 8 'meet the beltv at the roller 32. rlhe master film is sepa-rated from the' other' film which may accompany it, andthe abricbelt also, and passes over the roller 11 to the right, as viewed in Fig. 2a, and is eventually wound up on `the reel 13.

11n-electric rheostat 32 is'shown for the purpose .of controlling the electric motor dit lthe end thereof, and passing over a. roller 16 which operates the blower 5. A. cover 33l v may be provided in the central portion of the drying chamber 2 for the tpprpose of inspecting the junction point Wi sageway 9, and alsothe roller 11.

This apparatus is particularly adapted for .e Y.
